Kefron is a document and data management platform specializing in automating invoice processing, document scanning, and digital workflow solutions. This DIY Developer Guide for Kefron provides a step-by-step approach for building secure, scalable, and customized integrations with ERP systems, accounting platforms, and procurement solutions.

Prerequisites for Kefron Integrations

• Access to Kefron API documentation or integration guides
• API credentials (Client ID, Client Secret)
• Familiarity with:
  • RESTful APIs
  • OAuth 2.0 Authentication
  • JSON data formatting
• Tools: Postman, Swagger UI, SDKs (Python, Node.js)

Step 1: Authentication for Kefron Integrations

Kefron uses OAuth 2.0 for secure API access.

Example Authentication Request:

POST https://api.kefron.com/oauth2/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=YOUR_CLIENT_ID
&client_secret=YOUR_CLIENT_SECRET

The returned access token must be included in the Authorization header for all subsequent API calls.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Invoices
• Purchase Orders
• Suppliers
• Users and Permissions
• Document Uploads

Process:

• Review Kefron API documentation thoroughly.
• Map your internal fields (e.g., invoice number, supplier ID) to Kefron’s required fields.

Important considerations:

• Mandatory fields for invoices and documents
• Accurate handling of dates, currency formats, and tax fields
• Data validation rules for workflow automation

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to Kefron): POST to create invoices, upload documents, and register suppliers.
• Outbound (from Kefron): GET to retrieve invoice statuses, supplier lists, and audit logs.

Example: Creating an Invoice

POST /api/invoices
{
  "invoiceNumber": "INV12345",
  "supplierId": "SUP001",
  "amount": 1200.50,
  "currency": "USD",
  "dueDate": "2025-05-01"
}

Example: Retrieving Invoice Status

GET /api/invoices/INV12345/status
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture HTTP status codes and Kefron-specific error messages.
• Implement retries with exponential backoff for transient errors (5xx) and rate limiting (429).

Pagination:

• Use page and pageSize parameters when handling large data sets.

Example:

GET /api/invoices?page=2&pageSize=100

Step 5: Testing and Validation

• Test each API endpoint thoroughly with Postman.
• Validate invoice creation, document uploads, and status retrieval workflows.
• Stress-test bulk uploads and high-volume data pulls.

Step 6: Deployment and Security

• Deploy integrations on secure platforms (AWS, Azure, GCP).
• Store API credentials securely using a secret manager.
• Enforce HTTPS/TLS encryption for all API traffic.
• Implement detailed logging, audit trails, and real-time error monitoring.

Step 7: Maintenance and Monitoring

• Monitor API status updates from Kefron.
• Set up alerts for authentication failures or integration errors.
• Regularly audit transaction logs and success rates.

Optional Enhancements

• Integrate with ERP systems (SAP, Oracle, NetSuite) for automated invoice reconciliation.
• Use middleware (MuleSoft, Boomi) for complex workflows.
• Build dashboards for real-time document tracking and audit compliance.

Summary

Mastering Kefron integrations enables businesses to automate document workflows, improve accounts payable processes, and maintain regulatory compliance. This DIY Developer Guide for Kefron provides a structured framework for creating reliable, secure, and scalable integrations.
